5 | 865, 225 |
173, 45 |
∴ So the LCM of the given numbers is 5 x 173 x 45 = 38925
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/38925
Therefore, the GCF of Fractions 403/865,9971/225 is 13/38925
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 865,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(865,225) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(865,225) x common factors =5 x 1 = 5
LCM(865,225) = ( 865 × 225 ) / 5
LCM(865,225) = 194625 / 5
LCM(865,225) = 38925
